Boronia amplectens is a plant in the citrus family Rutaceae and is only known from two specimens collected from the Arnhem Land plateau in the Northern Territory of Australia. It is a sprawling shrub with narrow elliptic leaves and four-petalled flowers.
Boronia amplectens is a sprawling shrub that grows to 1sigfig=1NaNsigfig=1 wide. Its branches are covered with star-like hairs. The leaves are narrow elliptic, NaNsigfig=1NaNsigfig=1 long and NaNsigfig=1NaNsigfig=1 wide with a petiole NaNsigfig=1NaNsigfig=1 long. The flowers are usually arranged singly in leaf axils on a pedicel up to NaNsigfig=1NaNsigfig=1 long. The four sepals are larger than the petals, NaNsigfig=1NaNsigfig=1 long and NaNsigfig=1NaNsigfig=1 wide. The four petals are NaNsigfig=2NaNsigfig=2 long but increase in length as the fruit develops. Flowering has been observed in March and May and the fruit is a capsule about 4.5sigfig=1NaNsigfig=1 long and 2sigfig=1NaNsigfig=1 wide.[1]
Boronia amplectens was first formally described in 1997 by Marco Duretto who published the description in Australian Systematic Botany.[2] The specific epithet (amplectens) is derived from the Latin word amplector meaning "encircle", "enfold" or "embrace".[3]
This boronia is only known from two plants growing on the Arnhem Land plateau in the Northern Territory.
